Evariste Galois: French mathematician

3 mins read

Evariste Galois was a French mathematician who made significant contributions to the field of algebra and number theory. He is known for his work on group theory and the development of Galois theory, which is a branch of abstract algebra that studies the symmetries and structure of equations.

A brief history of Evariste Galois

Early Life and Education

Evariste Galois was born on October 25, 1811, in Bourg-la-Reine, France. He showed a remarkable aptitude for mathematics from a young age and quickly became a prodigy in the field. However, his formal education was interrupted by his involvement in political activities and his opposition to the July Monarchy, which led to his expulsion from school and imprisonment.

Galois Theory

Despite his tumultuous personal life, Galois made significant mathematical discoveries, particularly in the field of algebra. He developed the Galois theory, which is a groundbreaking theory that relates the roots of polynomial equations to their symmetries and provides a deep understanding of the solvability of polynomial equations by radicals. Galois theory is now considered one of the cornerstones of modern algebra and has applications in various fields, including cryptography, coding theory, and physics.

Contributions to Group Theory

Galois also made important contributions to group theory, which is a branch of mathematics that studies the properties and structure of symmetries. He developed the concept of a Galois group, which is a mathematical structure that represents the symmetries of a polynomial equation. Galois groups are used to study the solutions of polynomial equations and provide insights into the solvability of equations by radicals.


Évariste Galois died tragically at the age of 20 in a duel, leaving behind a legacy of groundbreaking mathematical work. His work on Galois theory and group theory laid the foundation for modern algebra and has had a profound impact on many areas of mathematics and its applications. Galois’ ideas were initially met with skepticism and were not fully appreciated during his lifetime, but his work gained recognition posthumously and has since become a fundamental part of mathematics. Today, Galois is considered one of the most important mathematicians in history, and his work continues to inspire and influence mathematicians and scientists around the world.
